The lubricant compositions of the rotatable parts such as bearing lubrication.In addition, it is related to enclose the rolling bearing of the lubricant compositions.
Background technology
In the past, in industrial circle, in order to seek the lubricant high performance used in the rotatable parts such as rolling bearing, taste
Try to coordinate various additives toward lubricant.When rolling bearing etc. is used under the high temperature conditions, the lubricating oil or profit of inclosure
There is deterioration by oxidation in consistent lubricant, lubricating film easily occurs rupture etc., and lubricating life has the worry for shortening.Particularly in high temperature and high speed bar
Under part, the rupture of lubricating film is easy to produce, or when ruptured, metal contact, heating, friction abrasion occurs between rotatable parts
A problem that increase, occurs.Therefore, the lubricating oil or grease used in rolling bearing etc., in order to improve high temperature durability,
As antioxidant, can individually or multiple combination is using amine system antioxidant, phenol system antioxidant, organic zinc compound etc..
For example, it is proposed that bearing with lubricator in, using 2,2 '-di-2-ethylhexylphosphine oxide (6- tert-butyl-4-methyl-Phenols) etc.
The sulfur system such as the amine system antioxidant such as phenol system antioxidant and octylated diphenylamine, phenothiazine antioxidant etc. is (with reference to patent
Document is 1).In addition, in the lubricant composition used in motor rolling bearing, in order to seek its low torque and quiet
Change, it is proposed that using low viscous ester oil as base oil, using metallic soap as thickening agent, as antioxidant and being obstructed with liquid
Amine and trithiophenyl phosphate (with reference to patent documentation 2).

Sealed by containment member 6, at least above-mentioned lubricant compositions 7 are enclosed around rotor 4.Lubrication groove 2, foreign steamer 3 and rotation
Body 4 is made up of the bearing steel as Ferrious material, as the lubricant compositions 7 of grease, between the plane of rotation with rotor 4
On be lubricated.
Fig. 1 is shown as the ball bearing of bearing, the rolling bearing of the present invention, it is also possible to roll using cylinder other than the above
Dynamic bearing, cone rolling, automatic aligning rolling bearing, needle-like rolling bearing, thrust rolling cylinder bearing, the rolling of thrust circular cone
Dynamic bearing, thrust needle-like rolling bearing, thrust automatic aligning rolling bearing etc..
The lubricant compositions of the present invention are bearing enclosed, due to having enclosed above-mentioned lubricant compositions, even if reaching 180
When using under the high temperature and high-speed condition more than DEG C, also can suppress the deterioration by oxidation of lubricant for a long time, reach the long-life.
Embodiment
The present invention passes through embodiment and comparative example is specifically illustrated, but the present invention is not by any limit of these examples
It is fixed.
Embodiment 1,1～comparative example of comparative example 6
With regard to the lubricant compositions in table 1, the measure of weight reduction rates when its high temperature durability is placed by high temperature
Evaluated.Base oil in table 1, any one are the miscella of alkyl diphenyl base ether oil and poly-alpha-olefin oil, its mixing ratio
Rate is with weight ratio as 8:2.For trying lubricant compositions in 180 DEG C and 120 DEG C of temperature chamber, place under air atmosphere gas,
In the time point for reaching 0,200,400,600,800,1000 hours (120 DEG C up to 600 hours), take out from temperature chamber, survey respectively
Determine weight, weight reduction rates are sought according to following formula.As a result table 1 is shown in the lump.In addition, 180 DEG C of high temperature is placed result of the test and is shown in figure
2,120 DEG C of high temperature is placed result of the test and is shown in Fig. 3.In each figure, transverse axis is minute (h), and the longitudinal axis is weight reduction rates (weight
Amount %).
Weight reduction rates (weight %)=100 × (weight (the g)-temperature chamber of the lubricant compositions before temperature chamber placement
The weight (g) of the lubricant compositions after placement)/temperature chamber place before lubricant compositions weight (g)
[table 1]
1)：Kinematic viscosity 97mm when loose village's oil studies 40 DEG C of made Moresco High Lube LB1002/s
2)：Kinematic viscosity 46mm during 40 DEG C of Nippon Steel chemistry society Shin-fluid8012/s
3)：2,2,4 trimethyl 1,2 dihydroquinoline polymer
4)：Octylated diphenylamine
5)：2,2 ＇-di-2-ethylhexylphosphine oxide (6- tert-butyl-4-methyl-Phenols)
Embodiment 2, embodiment 3, comparative example 7, and comparative example 8
With regard to lubricant compositions in table 2, weight reduction rates when its high temperature durability is placed by high temperature are determined and are carried out
Evaluate.Base oil in table 2 is alkyl diphenyl base ether oil and poly-alpha-olefin oil or the miscella of ester oil, its blending ratio (weight
Than) as shown in Table.In addition, the superscript in table 2 1)～it is 3) identical with table 1.For trying the perseverance that lubricant compositions are at 180 DEG C
In warm groove, place under air atmosphere gas, the time point for reaching 0,200,400 hours is taken out from temperature chamber, determines respective weight, according to
Above formula obtains weight reduction rates.As a result remember in the lump in table 2.In addition, same with 1 grade of embodiment, high temperature is placed result of the test and is shown
In Fig. 4.
[table 2]
6)：Kinematic viscosity 33.5mm during Hua Wangshe KAOLUBE26240 DEG C2/s
As table 1,2, and Fig. 2～4 shown in, using alkyl diphenyl base ether oil as the mixing base oil of main constituent in, coordinate conduct
Each embodiment of the quinoline system antioxidant of the regulation of antioxidant, coordinates other antioxidant when ratios with relatively the same base oil
Compared with, have confirmed that high temperature place test in weight reduction rates it is little, prolonged deterioration by oxidation can be suppressed.
Utilization probability in industry
The lubricant compositions of the present invention, turn as bearing used under the conditions of being made for high temperature (such as, more than 180 DEG C) etc.
The lubricant compositions of dynamic component lubrication, compatibly can utilize.
